Error report using a camera sdk for barcode scanning in C#

I have to develop an application which can help me in barcode scanning. I installed the solution of the Ozeki Camera SDK but i got a report that “unknown namespace Ozeki.Media.MediaHandlers.Video.CV.Processer reported” :surprised :disappoin

Seeing the report that you have inserted, I think you missed to add the necessary dll file to your references in your development interface, or the necessary using lines are missing at the beginning of the code.

I recommend you to check this C# source code for barcode snanning (camera-sdk.com/p_264-how-to-implement-barcode-scanning-from-the-stream-of-an-usb-camera-in-c-onvif.html) and study the quick start guide!
